Custom/Hybrid my stunt hull build

[Matt_E]

The 125 mains are too small. Stock is 130.

You should have:
70-72.5 pilots
135 mains
1.5 N&S
95g spring
1-1/4 low speeds
1-1/2 high speeds

That's a starting point, but should be close.

 

[chips]

so if they are too small why is it running so rich? because of the bigger low speeds??

 

[Matt_E]

What's your current popoff? It shouldn't be any lower than 35 psi.

 

[chips]

havent checked it yet. i know they were setup by team scream for a mildly ported 701, with everything else the same as my motor so i was hoping it would be pretty close.

 

[chips]

no video of the last ride but im getting more comfortable on it and i think its flipable. once i get my motor tuned a little better ill give it a shot and post some video of it. ive decided to move my battery to the front so its more accessible and to have that weight a little more forward.

 

[eastbay]

how could you sell it if it flips????

your ski is great! hope mine can be as nice as yours!

 

[chips]

lol well I haven't sold it yet.

Got an interesting one for you. When I first got my TLR cylinders back, Todd gave me some jetting specs to go with. I thought he was crazy. But after chasing the jetting around he was just about spot on.

105 pilot
130/135 mains
cannot remember if I kept the 1.5's or went to 2.0's.

At one point I tried the 75/135 or 80/135 setup. Smoked a piston shortly after. The 105 lows worked for my setup.

 

[Matt_E]

I don't doubt that at all for a ported cylinder.
The OP has a non-ported cylinder, though.

 

[chips]

soooo what do you guys think then. Try a little smaller pilot and see if that helps. That's what I'm thinking.

Time for A roll and a backflip.

A STOCK motor will have 70 pilots and 130 mains.
You have a pipe on there, which requires bigger mains, perhaps bigger pilots, and lower popoff.
You decide if you want smaller than stock mains on there.

(I do think the pilots are too big at 75, but those 125 mains would worry me)

 

[chips]

alright I'll do 135 mains and 70 pilots and see how much that helps.

 

[Matt_E]

It is an unported cylinder, right?

 

[chips]

correct

 

[Sanoman]

What happened to ya Chips!!????

 

[McDog]

He got it finished and running right so he doesn't need us anymore. Too busy riding I guess.

 

[Sanoman]

Kinda wondered what happened.

 

[McDog]

I'm just speculating.

 

[chips]

lol yea way to busy for you guys. No just been riding. Got it tuned pretty well. Runs awesome.
